Lidding, Pull-tab and Self-opening System

Abstract

Systems and methods are disclosed for a container with a lower wall portion to contain a liquid, gas or viscous material therein; an upper flange having an upper flange region; and a lid attached to the upper flange with at least a first region with a first bond strength to survive a drop test, and a second region with a second bond strength for easy opening.

1 . A container comprising:
 a lower wall portion to contain a liquid, gas or viscous material therein;   an upper flange having an upper flange region; and   a lid attached to the upper flange with at least a first region with a first bond strength to survive a drop test, and a second region with a second bond strength for easy opening.   
     
     
         2 . The container of  claim 1  wherein:
 the upper flange region contains a second region with a weak bond strength located outside the first region to easily open the container when pulling on a tab. 
 
     
     
         3 . The container of  claim 1  wherein:
 the lid comprises a second centrally located lid attached thereon and openable by pulling on a tab connected to a second lid, and wherein the second centrally located lid has coverage to survive the drop test. 
 
     
     
         4 . The container of  claim 3  wherein:
 the first lid has a pre-opening aperture lying directly below the second lid. 
 
     
     
         5 . The container of  claim 1  wherein:
 the lid includes a tab outside the first region with the first bond strength, wherein the tab includes at least one pre-weakened point to initiate a tear across the lid. 
 
     
     
         6 . The container of  claim 1  further comprising:
 a second outer rigid container having a durable cap with a self-opening system that punctures or severs a portion of the lid. 
 
     
     
         7 . The container of  claim 1  further comprising:
 a second outer rigid container with a durable cap including at least one of the following: a pump system or a spray system. 
 
     
     
         8 . The container of  claim 1  wherein:
 the upper flange contains one or more handling ears. 
 
     
     
         9 . The container of  claim 1  wherein:
 differences in bonding strength are formed with differential adhesives, differential sealing properties, or treatment processes. 
 
     
     
         10 . The container of  claim 1  wherein:
 the lid's film quality and orientation propagate a straight line tear. 
 
     
     
         11 . The container of  claim 6  wherein:
 the container operates with a stemless pump or spray. 
 
     
     
         12 . A dispensing system comprising:
 a first container comprising a lower wall portion to contain a liquid, gas or viscous material therein; and   an upper flange seated atop a second outer rigid container with a cap that contains a self-piercing system to pierce an underlying lid membrane.   
     
     
         13 . The dispenser of  claim 12  wherein:
 the self-piercing system is actuated by pushing downwardly into a lid membrane. 
 
     
     
         14 . The dispenser of  claim 12  wherein:
 the self-piercing system is actuated by screwing a cap onto the second rigid container and piercing a lid membrane as a cap is secured on the first container. 
 
     
     
         15 . The dispenser of  claim 12  wherein:
 the self-piercing system is an integral part of a spray head unit, or a pump unit. 
 
     
     
         16 . The dispenser of  claim 12  wherein:
 the self-piercing system is an integral part of a nozzle. 
 
     
     
         17 . A method of dispensing a material comprising:
 providing a first sealed container containing a liquid, gas or viscous material therein;   sealing the container with a lidding membrane;   providing a second outer rigid container comprising a cap with a self-piercing device;   placing the first sealed container into the second outer rigid container;   securely fastening the cap to the outer rigid container and;   actuating the self-piercing device to dispense the material.   
     
     
         18 . The method of  claim 17  further comprising:
 actuating the self-piercing device as the cap is secured to the outer rigid container. 
 
     
     
         19 . The method of  claim 17  wherein:
 the cap comprises a pump or spray head. 
 
     
     
         20 . The method of  claim 17  wherein:
 the outer container is sufficiently flexible to squeeze a liquid, gas or viscous material out of an exit port.
